To say Russell makes films on biology is sort of like saying Rodin threw some clay on a table and a few minutes later came up with a figure representative of a human. 'Light Microscope' starts out didactically (Russell was a former K-12 biology teacher) in instructing the student on proper microscope technique, then goes off into the hyperspace of lighting techniques, using light and colored filters, that make otherwise difficult-to-see phenomena visible. This film, frankly, borders on psychedelia, and shows the technology Russell himself uses to make his visually arresting films.
